\text{Write in y=mx+c form, where  m is the slope and c is the y-intercept}\\\\~~~~18x-y = 5\\\\\implies y = 18x -5\\\\\text{y-intercept}~ = -5

Answer:

y-intercept = -5

Step-by-step explanation:

Slope-intercept form of a linear equation:  y = mx + b

(where m is the slope and b is the y-intercept)

In order to find the y-intercept of the given line, rearrange so that it is in slope-intercept form:

Given equation:

18x-y=5

Add y to both sides:  

\implies 18x-y+y=5+y

\implies 18x=5+y

Subtract 5 from both sides:

\implies 18x-5=5+y-5

\implies 18x-5=y

In slope-intercept form:

\implies y=18x-5

Therefore,

  • slope (m) = 18
  • y-intercept (b) = -5

Patrick went cycling one weekend.
Margarita [4]
For this question, it would be most effective to use an algebraic expression to more easily show what the question is asking. If we use the variable "k" to show the distance in km that he cycled on Sunday, we know that the amount he cycled on Saturday equals k + 12, and the amount that he cycled on the weekend should be the amount of Saturday plus the amount of Sunday. If we write this as an equation we say:
k + k + 12 = 38
=> 2k + 12 = 38
Now we can just rearrange and solve for k:
=> 2k = 26
=> k = 26/2 = 13
Therefore Patrick cycled 13km on Sunday
To solve the answer, we just add 12km to the value for Sunday like so:
12 + 13 = the amount he cycled on Sunday
Hope this helped, remember to please try and understand the maths as well as the answer :))

PLEASE HELP , TRYING TO BE ON HONOR ROLL !

Option A

The solution is (0, \frac{-1}{4})

<em><u>Solution:</u></em>

<em><u>Given system of equations are:</u></em>

3x + 6y = 1 ------ eqn 1

x - 4y = 1 ------ eqn 2

We have to find solution to system of equations

We can use substitution method

From eqn 2,

x = 1 + 4y -------- eqn 3

Substitute eqn 3 in eqn 1

3(1 + 4y) + 6y = 1

3 + 12y + 6y = 1

18y = 1 - 3

18y = -2

Divide both sides by 18

y = \frac{-2}{18}\\\\y = \frac{-1}{4}

Substitute the above value of y in eqn 3

x = 1 + 4 \times \frac{-1}{4}\\\\x = 1-1\\\\x = 0

Thus solution is (0, \frac{-1}{4})

Brums [2.3K]

Answer:

m = E/c²

Step-by-step explanation:

E = mc²

mc² = E

Divide both sides by c².

m = E/c²

What is 4/7 of 210? please tell me I need to KNOW!!!!!. Please write your answer in simplest form
Anton [14]
It is 120 because you have to divide 210 by 7 which is 30 then multiply by 4 so 30 x 4 = 120.
